+\section{Version macros}\label{versionfunctions}
+
+The following constants are defined in wxWidgets:
+
+\begin{itemize}\itemsep=0pt
+\item {\tt wxMAJOR\_VERSION} is the major version of wxWidgets
+\item {\tt wxMINOR\_VERSION} is the minor version of wxWidgets
+\item {\tt wxRELEASE\_NUMBER} is the release number
+\item {\tt wxSUBRELEASE\_NUMBER} is the subrelease number which is $0$ for all
+official releases
+\end{itemize}
+
+For example, the values or these constants for wxWidgets 2.1.15 are 2, 1 and
+15.
+
+Additionally, {\tt wxVERSION\_STRING} is a user-readable string containing
+the full wxWidgets version and {\tt wxVERSION\_NUMBER} is a combination of the
+three version numbers above: for 2.1.15, it is 2115 and it is 2200 for
+wxWidgets 2.2.
+
+The subrelease number is only used for the sources in between official releases
+and so normally is not useful.
+
+\wxheading{Include files}
+
+<wx/version.h> or <wx/defs.h>
+
+
+\membersection{wxCHECK\_GCC\_VERSION}\label{wxcheckgccversion}
+
+\func{bool}{wxCHECK\_GCC\_VERSION}{\param{}{major, minor, release}}
+
+Returns $1$ if the compiler being used to compile the code is GNU C++
+compiler (g++) version major.minor.release or greater. Otherwise, and also if
+the compiler is not GNU C++ at all, returns $0$.
+
+
+\membersection{wxCHECK\_VERSION}\label{wxcheckversion}
+
+\func{bool}{wxCHECK\_VERSION}{\param{}{major, minor, release}}
+
+This is a macro which evaluates to true if the current wxWidgets version is at
+least major.minor.release.
+
+For example, to test if the program is compiled with wxWidgets 2.2 or higher,
+the following can be done:
+
+\begin{verbatim}
+ wxString s;
+#if wxCHECK_VERSION(2, 2, 0)
+ if ( s.StartsWith("foo") )
+#else // replacement code for old version
+ if ( strncmp(s, "foo", 3) == 0 )
+#endif
+ {
+ ...
+ }
+\end{verbatim}
+
+
+\membersection{wxCHECK\_VERSION\_FULL}\label{wxcheckversionfull}
+
+\func{bool}{wxCHECK\_VERSION\_FULL}{\param{}{major, minor, release, subrel}}
+
+Same as \helpref{wxCHECK\_VERSION}{wxcheckversion} but also checks that
+\texttt{wxSUBRELEASE\_NUMBER} is at least \arg{subrel}.
+
+
+\membersection{wxCHECK\_W32API\_VERSION}\label{wxcheckw32apiversion}
+
+\func{bool}{wxCHECK\_GCC\_VERSION}{\param{}{major, minor, release}}
+
+Returns $1$ if the version of w32api headers used is major.minor.release or
+greater. Otherwise, and also if we are not compiling with mingw32/cygwin under
+Win32 at all, returns $0$.
+
+
+
+\section{Application initialization and termination}\label{appinifunctions}
+
+The functions in this section are used on application startup/shutdown and also
+to control the behaviour of the main event loop of the GUI programs.
+
+
+\membersection{::wxEntry}\label{wxentry}
+
+This initializes wxWidgets in a platform-dependent way. Use this if you are not
+using the default wxWidgets entry code (e.g. main or WinMain). For example, you
+can initialize wxWidgets from an Microsoft Foundation Classes application using
+this function.
+
+The following overload of wxEntry is available under all platforms:
+
+\func{int}{wxEntry}{\param{int\&}{ argc}, \param{wxChar **}{argv}}
+
+Under MS Windows, an additional overload suitable for calling from
+\texttt{WinMain} is available:
+
+\func{int}{wxEntry}{\param{HINSTANCE }{hInstance}, \param{HINSTANCE }{hPrevInstance = \NULL}, \param{char *}{pCmdLine = \NULL}, \param{int }{nCmdShow = \texttt{SW\_SHOWNORMAL}}}
+
+(notice that under Windows CE platform, and only there, the type of
+\arg{pCmdLine} is \texttt{wchar\_t *}, otherwise it is \texttt{char *}, even in
+Unicode build).
+
+\wxheading{See also}
+
+\helpref{wxEntryStart}{wxentrystart}
+
+\wxheading{Remarks}
+
+To clean up wxWidgets, call wxApp::OnExit followed by the static function
+wxApp::CleanUp. For example, if exiting from an MFC application that also uses wxWidgets:
+
+\begin{verbatim}
+int CTheApp::ExitInstance()
+{
+ // OnExit isn't called by CleanUp so must be called explicitly.
+ wxTheApp->OnExit();
+ wxApp::CleanUp();
+
+ return CWinApp::ExitInstance();
+}
+\end{verbatim}
+

+\membersection{::wxEntryCleanup}\label{wxentrycleanup}
+
+\func{void}{wxEntryCleanup}{\void}
+
+Free resources allocated by a successful call to \helpref{wxEntryStart}{wxentrystart}.

+
+<wx/init.h>
+
+
+\membersection{::wxEntryStart}\label{wxentrystart}
+
+\func{bool}{wxEntryStart}{\param{int\&}{ argc}, \param{wxChar **}{argv}}
+
+This function can be used to perform the initialization of wxWidgets if you
+can't use the default initialization code for any reason.
+
+If the function returns \true, the initialization was successful and the global
+\helpref{wxApp}{wxapp} object \texttt{wxTheApp} has been created. Moreover,
+\helpref{wxEntryCleanup}{wxentrycleanup} must be called afterwards. If the
+function returns \false, a catastrophic initialization error occured and (at
+least the GUI part of) the library can't be used at all.
+
+Notice that parameters \arg{argc} and \arg{argv} may be modified by this
+function.
+
+\wxheading{Include files}
+
+<wx/init.h>
+
+
+\membersection{::wxGetApp}\label{wxgetapp}
+
+\func{wxAppDerivedClass\&}{wxGetApp}{\void}
+
+This function doesn't exist in wxWidgets but it is created by using
+the \helpref{IMPLEMENT\_APP}{implementapp} macro. Thus, before using it
+anywhere but in the same module where this macro is used, you must make it
+available using \helpref{DECLARE\_APP}{declareapp}.
+
+The advantage of using this function compared to directly using the global
+wxTheApp pointer is that the latter is of type {\tt wxApp *} and so wouldn't
+allow you to access the functions specific to your application class but not
+present in wxApp while wxGetApp() returns the object of the right type.
+
+
+\membersection{::wxHandleFatalExceptions}\label{wxhandlefatalexceptions}
+
+\func{bool}{wxHandleFatalExceptions}{\param{bool}{ doIt = true}}
+
+If {\it doIt} is true, the fatal exceptions (also known as general protection
+faults under Windows or segmentation violations in the Unix world) will be
+caught and passed to \helpref{wxApp::OnFatalException}{wxapponfatalexception}.
+By default, i.e. before this function is called, they will be handled in the
+normal way which usually just means that the application will be terminated.
+Calling wxHandleFatalExceptions() with {\it doIt} equal to false will restore
+this default behaviour.
+
+
+\membersection{::wxInitAllImageHandlers}\label{wxinitallimagehandlers}
+
+\func{void}{wxInitAllImageHandlers}{\void}
+
+Initializes all available image handlers. For a list of available handlers,
+see \helpref{wxImage}{wximage}.
+
+\wxheading{See also}
+
+\helpref{wxImage}{wximage}, \helpref{wxImageHandler}{wximagehandler}
+
+\wxheading{Include files}
+
+<wx/image.h>
+
+
+\membersection{::wxInitialize}\label{wxinitialize}
+
+\func{bool}{wxInitialize}{\void}
+
+This function is used in wxBase only and only if you don't create
+\helpref{wxApp}{wxapp} object at all. In this case you must call it from your
+{\tt main()} function before calling any other wxWidgets functions.
+
+If the function returns \false the initialization could not be performed,
+in this case the library cannot be used and
+\helpref{wxUninitialize}{wxuninitialize} shouldn't be called neither.
+
+This function may be called several times but
+\helpref{wxUninitialize}{wxuninitialize} must be called for each successful
+call to this function.
+
+\wxheading{Include files}
+
+<wx/app.h>
+
+
+\membersection{::wxSafeYield}\label{wxsafeyield}
+
+\func{bool}{wxSafeYield}{\param{wxWindow*}{ win = NULL}, \param{bool}{
+ onlyIfNeeded = false}}
+
+This function is similar to wxYield, except that it disables the user input to
+all program windows before calling wxYield and re-enables it again
+afterwards. If {\it win} is not NULL, this window will remain enabled,
+allowing the implementation of some limited user interaction.
+
+Returns the result of the call to \helpref{::wxYield}{wxyield}.
+
+\wxheading{Include files}
+
+<wx/utils.h>
+
+
+\membersection{::wxUninitialize}\label{wxuninitialize}
+
+\func{void}{wxUninitialize}{\void}
+
+This function is for use in console (wxBase) programs only. It must be called
+once for each previous successful call to \helpref{wxInitialize}{wxinitialize}.
+
+\wxheading{Include files}
+
+<wx/app.h>
+
+
+\membersection{::wxYield}\label{wxyield}
+
+\func{bool}{wxYield}{\void}
+
+Calls \helpref{wxApp::Yield}{wxappyield}.
+
+This function is kept only for backwards compatibility. Please use
+the \helpref{wxApp::Yield}{wxappyield} method instead in any new code.

+<wx/app.h> or <wx/utils.h>
+
+
+\membersection{::wxWakeUpIdle}\label{wxwakeupidle}
+
+\func{void}{wxWakeUpIdle}{\void}
+
+This functions wakes up the (internal and platform dependent) idle system, i.e. it
+will force the system to send an idle event even if the system currently {\it is}
+ idle and thus would not send any idle event until after some other event would get
+sent. This is also useful for sending events between two threads and is used by
+the corresponding functions \helpref{::wxPostEvent}{wxpostevent} and
+\helpref{wxEvtHandler::AddPendingEvent}{wxevthandleraddpendingevent}.
+

+\section{Process control functions}\label{processfunctions}
+
+The functions in this section are used to launch or terminate the other
+processes.
+
+
+\membersection{::wxExecute}\label{wxexecute}
+
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{int }{sync = wxEXEC\_ASYNC}, \param{wxProcess *}{callback = NULL}}
+
+\perlnote{In wxPerl this function is called \texttt{Wx::ExecuteCommand}}
+
+\func{long}{wxExecute}{\param{char **}{argv}, \param{int }{flags = wxEXEC\_ASYNC}, \param{wxProcess *}{callback = NULL}}
+
+\perlnote{In wxPerl this function is called \texttt{Wx::ExecuteArgs}}
+
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{wxArrayString\& }{output}, \param{int }{flags = 0}}
+
+\perlnote{In wxPerl this function is called \texttt{Wx::ExecuteStdout} and it
+only takes the {\tt command} argument,
+and returns a 2-element list {\tt ( status, output )}, where {\tt output} is
+an array reference.}
+
+\func{long}{wxExecute}{\param{const wxString\& }{command}, \param{wxArrayString\& }{output}, \param{wxArrayString\& }{errors}, \param{int }{flags = 0}}
+
+\perlnote{In wxPerl this function is called \texttt{Wx::ExecuteStdoutStderr}
+and it only takes the {\tt command} argument,
+and returns a 3-element list {\tt ( status, output, errors )}, where
+{\tt output} and {\tt errors} are array references.}
+
+Executes another program in Unix or Windows.
+
+The first form takes a command string, such as {\tt "emacs file.txt"}.
+
+The second form takes an array of values: a command, any number of
+arguments, terminated by NULL.
+
+The semantics of the third and fourth versions is different from the first two
+and is described in more details below.
+
+If {\it flags} parameter contains {\tt wxEXEC\_ASYNC} flag (the default), flow
+of control immediately returns. If it contains {\tt wxEXEC\_SYNC}, the current
+application waits until the other program has terminated.
+
+In the case of synchronous execution, the return value is the exit code of
+the process (which terminates by the moment the function returns) and will be
+$-1$ if the process couldn't be started and typically 0 if the process
+terminated successfully. Also, while waiting for the process to
+terminate, wxExecute will call \helpref{wxYield}{wxyield}. Because of this, by
+default this function disables all application windows to avoid unexpected
+reentrancies which could result from the users interaction with the program
+while the child process is running. If you are sure that it is safe to not
+disable the program windows, you may pass \texttt{wxEXEC\_NODISABLE} flag to
+prevent this automatic disabling from happening.
+
+For asynchronous execution, however, the return value is the process id and
+zero value indicates that the command could not be executed. As an added
+complication, the return value of $-1$ in this case indicates that we didn't
+launch a new process, but connected to the running one (this can only happen in
+case of using DDE under Windows for command execution). In particular, in this,
+and only this, case the calling code will not get the notification about
+process termination.
+
+If callback isn't NULL and if execution is asynchronous,
+\helpref{wxProcess::OnTerminate}{wxprocessonterminate} will be called when
+the process finishes. Specifying this parameter also allows you to redirect the
+standard input and/or output of the process being launched by calling
+\helpref{Redirect}{wxprocessredirect}. If the child process IO is redirected,
+under Windows the process window is not shown by default (this avoids having to
+flush an unnecessary console for the processes which don't create any windows
+anyhow) but a {\tt wxEXEC\_NOHIDE} flag can be used to prevent this from
+happening, i.e. with this flag the child process window will be shown normally.
+
+Under Unix the flag {\tt wxEXEC\_MAKE\_GROUP\_LEADER} may be used to ensure
+that the new process is a group leader (this will create a new session if
+needed). Calling \helpref{wxKill}{wxkill} passing wxKILL\_CHILDREN will
+kill this process as well as all of its children (except those which have
+started their own session).
+
+Finally, you may use the third overloaded version of this function to execute
+a process (always synchronously, the contents of \arg{flags} is or'd with
+\texttt{wxEXEC\_SYNC}) and capture its output in the array \arg{output}. The
+fourth version adds the possibility to additionally capture the messages from
+standard error output in the \arg{errors} array.
+
+{\bf NB:} Currently wxExecute() can only be used from the main thread, calling
+this function from another thread will result in an assert failure in debug
+build and won't work.

+\membersection{::wxExit}\label{wxexit}
+
+\func{void}{wxExit}{\void}
+
+Exits application after calling \helpref{wxApp::OnExit}{wxapponexit}.
+Should only be used in an emergency: normally the top-level frame
+should be deleted (after deleting all other frames) to terminate the
+application. See \helpref{wxCloseEvent}{wxcloseevent} and \helpref{wxApp}{wxapp}.

+
+\func{int}{wxKill}{\param{long}{ pid}, \param{int}{ sig = wxSIGTERM}, \param{wxKillError }{*rc = NULL}, \param{int }{flags = 0}}
+
+Equivalent to the Unix kill function: send the given signal {\it sig} to the
+process with PID {\it pid}. The valid signal values are
+
+\begin{verbatim}
+enum wxSignal
+{
+ wxSIGNONE = 0, // verify if the process exists under Unix
+ wxSIGHUP,
+ wxSIGINT,
+ wxSIGQUIT,
+ wxSIGILL,
+ wxSIGTRAP,
+ wxSIGABRT,
+ wxSIGEMT,
+ wxSIGFPE,
+ wxSIGKILL, // forcefully kill, dangerous!
+ wxSIGBUS,
+ wxSIGSEGV,
+ wxSIGSYS,
+ wxSIGPIPE,
+ wxSIGALRM,
+ wxSIGTERM // terminate the process gently
+};
+\end{verbatim}
+
+{\tt wxSIGNONE}, {\tt wxSIGKILL} and {\tt wxSIGTERM} have the same meaning
+under both Unix and Windows but all the other signals are equivalent to
+{\tt wxSIGTERM} under Windows.
+
+Returns 0 on success, -1 on failure. If {\it rc} parameter is not NULL, it will
+be filled with an element of {\tt wxKillError} enum:
+
+\begin{verbatim}
+enum wxKillError
+{
+ wxKILL_OK, // no error
+ wxKILL_BAD_SIGNAL, // no such signal
+ wxKILL_ACCESS_DENIED, // permission denied
+ wxKILL_NO_PROCESS, // no such process
+ wxKILL_ERROR // another, unspecified error
+};
+\end{verbatim}
+
+The {\it flags} parameter can be wxKILL\_NOCHILDREN (the default),
+or wxKILL\_CHILDREN, in which case the child processes of this
+process will be killed too. Note that under Unix, for wxKILL\_CHILDREN
+to work you should have created the process by passing wxEXEC\_MAKE\_GROUP\_LEADER
+to wxExecute.
